Testing a new antibody to treat chronic hepatitis B infection

First-in-human study of a potent anti-HBsAg neutralizing antibody

NIH-funded research Rockefeller University · NIH-11035143

This study is testing a new treatment that uses a special antibody to help lower the levels of hepatitis B in people with chronic hepatitis B, with the hope of boosting their immune system and moving closer to a cure.

What this research studies

This research investigates a novel human monoclonal antibody designed to neutralize the hepatitis B surface antigen (HBsAg), which is crucial in managing chronic hepatitis B infection. The study aims to assess the antibody's ability to reduce HBsAg levels in patients, potentially restoring their immune response against the virus. By decreasing HBsAg, the research hopes to alleviate immune exhaustion and promote a functional cure for chronic hepatitis B. Participants will receive the antibody treatment and be monitored for its effectiveness and safety.

Who could benefit from this research

Good fit: Ideal candidates for this research are individuals diagnosed with chronic hepatitis B infection who have not responded adequately to existing antiviral therapies.

Not a fit: Patients with acute hepatitis B infection or those who have already achieved a functional cure may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to a new treatment option that helps clear hepatitis B virus from the body and improves patients' immune responses.

How similar studies have performed: Previous research has shown promise with antibody therapies in treating viral infections, suggesting potential success for this novel approach in hepatitis B.
